When I started in 1967 there was grass rwys 24/06 and 18/36. 24/06 certainly is not parallel to 26/08 but if we trusted the bloke in the light aircraft we would treat it so. 'Clear to land 24, if the event of a go-around remain north of the main' was the phrase used. :-)
Left circuits on 06 were interesting. Left base would cross through the final app for 08 and then final would cross over the runway again. Again, if you trusted the person then you could ask the light aircraft to remain north of the 08 approach.
All good fun. Wouldn't get away with it now!
